For the world's top long jump athletes, the approach distance must be at least 45 meters, otherwise they will not be able to obtain sufficient approach speed, and the final long jump results will naturally be less than ideal.

In the sprint long jump event, most domestic and foreign sports science researchers generally believe that the approach speed plays an absolute role in the long jump performance.

In "Research on the Training Content System of Chinese High-Level Long Jump Athletes" written by Feng Shuyong, it is mentioned that the athlete's approach speed is highly correlated with the long jump performance, R=0.96.

Of course, this relationship is not absolute, and some experts believe that among the factors that affect long jump performance, approach speed accounts for about 70%.

However, according to the statistics of a large number of athletes' competition data, it can be seen that when other factors remain unchanged, the approach speed must be positively correlated with the long jump performance.

The athlete's absolute flat running speed is the basis of the approach speed. Only with a high absolute speed can a relatively high approach speed be achieved.

At the 1997 World Athletics Championships in Athens, the average final pedal speed of athletes who entered the long jump final was: 9.52 m/s for women, and 10.66 m/s for men. The average speeds of the top four men and the top three women were even higher.

It reached 10.75 meters/second and 9.66 meters/second.

In contrast, China's long jump athletes are far behind the world's top long jump athletes.

At the Eighth National Games in 1997, the average final pedal speeds of male and female long jump finalists were: 9.78 m/s and 8.74 m/s respectively.

So this is why the world's top long jumpers are not bad at 100 meters.

Randy Huntington once mentioned that his best disciple, Michael Powell, has a 100-meter ability of about 10.30 seconds.

As one of the greatest long jumpers in the history of track and field, Carl Lewis's best time in the 100 meters was 9.86 seconds.

In the distant 1930s, [Black Lightning] Jesse Owens was also the world's top sprinter and long jump athlete at the time, holding both the 100-meter and long jump world records while in service.

This is why Wen set the starting point after 50 meters, because he needs to gain a higher approach speed through a longer approach run.

When he stood at the starting point he set, the long jump athletes couldn't help but take a breath of air, because this approach distance was something they didn't dare to try easily.

The longer the approach distance, the faster the athlete can achieve, but this is based on sufficient flat running ability.

For these teenagers whose long jump scores are generally around 7 meters on the court, a run-up distance of more than 50 meters will not only fail to allow them to achieve a faster run-up speed, but will be counterproductive and will seriously consume their physical strength.

Even the 51-meter run-up distance is a bit reluctant for the current Wei En. With 6 jumps at full strength, the energy consumed will definitely not be less than running 100 meters with 2 shots at full strength.

Two jumps, if everything goes well, he only jumps twice!

"Snapped--!"

Wayne turned around to face the stands on the right, raised his hands above his head and clapped his hands, and immediately the "sensible" audience followed his rhythm and applauded.

After a while, almost the entire audience started playing the rhythm enthusiastically, led by Wei En.

"Pah——!" "Pah——!" "Pah——!"

After each round of clapping, the next interlude will become faster, just like the pace of an athlete gradually increasing when running and accelerating.

Wei En started, pushing and stretching, swinging his arms, scraping the ground, and speeding up.

After 20 meters, the upper body and trunk are completely erect, the head is completely raised, and the eyes are looking straight ahead.

In the 100-meter event, Wei En's running technique was more focused on the back side, but at this time, Wei En changed to the front side technique.

The approach distance of the long jump is only so long in total. In order to obtain faster absolute speed, it is a relatively ideal choice to focus on front side technology.

The distance to the take-off board is getting closer and closer, 25 meters...20 meters...16 meters...

There is a green marker placed by Wayne at a distance of 14.9 from the take-off board. It is also the only marker placed so close to the take-off board in the field.

Naturally, this marker is not used to mark the starting point, but the sixth-to-last step marker point set by Wei En for himself. The purpose is to remind himself to control the step length and rhythm to ensure the accuracy and smoothness of the pedal.

In the system, Wei En has rehearsed his first jump of the season countless times. He is already familiar with the setting of the starting point, the setting of the last six mark points, the setting of the take-off angle, and the setting of the flying action.

Although it had been eight months since he last officially participated in the long jump competition, when he took the first step amidst the applause of the audience, he knew...

This jump is there!

"Snapped--!"

Pedal, take off, fly into the air!

The wind speed is 2.3m/s, the take-off angle is 22.8°, the maximum approach speed is 11.56m/s, the final pedal speed is 10.80m/s, and the approach utilization rate is 93.4%, reaching the level of the world's outstanding long jump athletes!

After soaring into the air, just like the technical movements of a 100-meter run, push and extend the legs first straighten, then start to fold inward, swing the legs to complete the hip lift first, and then swing down.

After completing this set of [air step] movements, swing both legs backward at the same time to form a straight posture in the air.

Then tighten your abdomen and raise your legs, swing your arms upward and forward, downward and backward, ready to land.

"oh----!!"

As the audience in the stadium kept screaming, Wei En suddenly fell into the sand pit. After the fine sand was raised, Wei En turned around and saw his final landing point clearly. He immediately raised his arms and shouted

This chapter is not over yet, please click on the next page to continue reading! "8 meters! Player Wei En jumped 8 meters! The referee indicated that the result is valid!"

"Incredible, while other contestants were still struggling around 7 meters, Wei En's first jump of the season actually jumped over 8 meters!"

"We now have to wait for the referees' measurement confirmation. During this period, I would like to remind everyone that Wei En is under 17 years old this year, and this jump has already set a new national juvenile record!"

"In addition, the national long jump youth record is Zhang Xiaoyi's jump of 8.17 meters in the 2006 National Grand Prix Chongqing Station. Judging from the naked eye, Wei En's jump should not be much different..."

"8 meters 20! The wind speed is 1.3 meters per second, the result is valid! A new national youth long jump record was born!! Everyone, where are the cheers??!!"

...

Amidst the cheers and congratulations of the audience, Wei En also smiled and applauded himself. The troubles caused by yesterday's unsatisfactory results in the 100-meter event have now disappeared.

The wind speed of 1.3m/s is a little bit high. When Zhang Xiaoyi jumped 8.17 meters in the 2006 National Grand Prix Chongqing Station, the wind speed was only 0.5.

However, according to the regulations of the IAAF, when the wind speed of the jumping event is ≤ 2.0m/s, the results and records will be recognized.

When 2.0m/s < wind speed ≤ 7.2m/s, the athlete's results will still be recognized, but if a certain record is broken, it will not be recognized.

The reason why he tried to set the approach distance to 51 meters on the first jump of the season today was because he was aiming at Zhang Xiaoyi's national youth record.
